Correct neither of them have the metal in them and a lot of people use them for BP grease.

I have just gone away from grease myself because in my feeble mind I still remember a bit of staining (baked grease into and on the bore) which was not a realy problem, but I also do not like the dealing with the goo or the posibliltiy of contaminating some powder. There are a lot of folks out there being very successful with BP grease.
